JOSEPH VOYLE, OF GAIN ESVILLE, FLORIDA.

RICE-HULLER.

SPECIFICATION forming part of Letters Patent No. 243,016, dated June 14, 1881. Application filed February 16, 1880.

To all 'whom it may concern:

Be it known that I, J osEPH VoYLE, of Gainesville, in the county of Alach ua and State of Florida, have invented anewand Improved Rice-Huller 5 and I do hereby declare `that the following is a full, clear, and exact description ofthe same.

The object ot' my invention is to furnish an improved rice-hnller'which is simple `and inexpensive, and which will remove the hull from the rice lnore thoroughly and with b ut little loss froln broken grains.v

The invention consists of a hard grooved roller having its axis at an angle tothe axis of a large roller whose surface is soft and yielding; and it further consists of a roller grooved or provided with grain-holding face formed by Winding wire spirally upon a roller or cylinder, as hereinafter fully described.

In the drawings, Figure 1 is a perspective view, with the frame partially broken away to show the working parts. Fig. 2 is a vertical section parallel with the axle of the roller A. Fig. 3 is a vertical section at right angles to Fig. 2. Fig. .tis a modification showing three grooved rollers.

In the drawings, A represents a large roller having a soft or yielding surface, a, mounted uponthe frame E. i

C is a pulley upon the axle of the roller A. The sott or yielding surface a ot' this roller is formed by securing sections of soft wood endwise between two disks of hard wood, so that the sections will present the end of the grain of the wood on the periphery of the roller. Instead of sections of wood, a soft or yielding surface'may'be formed by winding strips of leather on a roller. I have also obtained a good yielding surface by cutting the entire roller from a tree having a soft sap wood and a hard heart, thereby obtaining the axle body and surface in one piece. When the surface is not uniformly elastic I wet the hard parts and beat them while wet until they possess the same degree of elasticity as the other parts.

B is a roller of hard wood mounted in the hinged frame E, so that its axis will be at an angle to the axis of the roller A, whereby the faces of the rollers at the line of contact will have a divergent motion. Upon this roller I wind Wire spirally, thereby forming a spirallygrooved surface. By this means I obtain a cheap and durable grooved or grain-holding surface, and one which I find gives better sat' isfaction than when made entirely of wood. It holds the grain better, and, owing to the wire being hard and smooth, the grain slips easily over it and out of the machine.

The roller B is shown driven by frictional contact with the roller A; but any other suitable means may be employed.

The action of the rollers is as follows The rice being passed between them, it is seized by both surfaces, partially embedding itself in one and entering the grooves of the other roller,

Veach holding it during divergence with sufficient iirmness to pull its part ofthe hull off in its own direction.

I am aware thatit is not broadly new to mount the rollers so that one axis is at an angle to the other, and I do not claim, broadly, rollers mountedin thisway; but I have found by experience that a hard grooved and a soft or yielding surface revolving in Contact one at an angle to the other produces the best pos sible results.

What I therefore claim, and desire to secure by Letters Patent, is l 1. The combination, in a rice-huller, of the roller A, having a soft or yielding surface, and the hard grooved roller B, set at an angle to the said roller A, substantially as herein shown and described.

2. In a rice-huller, the combination, with the l frame E E and the roller A, provided with a soft or yieldin g surface, of the roller B, mounted in the frame with its axis at an angle tothe roller A, and having its grain-holding face formed by wire wrapped spirally upon it, sub stantially as and for the purpose set forth.
